Regardless of what anyone is telling you or what inspirational messages they send you. It's a demon only you can fight and must ultimately defeat alone.
Think of it more as you being the hero in your quest, your support structures; friends, family, strangers (and yes medication) are there to help you stay up when times get overwhelming and you need that push - which is why I absolutely implore any one who is on medication to also get a therapist - but yes you have to be the one who "slays the beast", think of everyone else as your fellowship or band of merry-men.
